to be honest this can happen at any station or to any car, I have the same problem with my ML and i found it usually happens when the pump nozzle is pushed into the tank as far as possible, generally i pull the pump out a half inch or so and it fixes the problem. my theory is the angle when pushed in all the way might cause some gas to splash off who knows what and would trick the pump into stopping because it thinks the tank is full.
hopefully this helps.
